摘要： An optical transceiver module is provided with an elongated delatching pull tab that that enables an optical transceiver module to be easily delatched and pulled from a cage without having to first unplug optical fiber cables from the module and without having to rotate a bail. Thus, the number of manual actions that need to be performed by a user to remove the module from a cage is drastically reduced, which makes simplifies the removal process and makes the design well suited for use in hot-pluggable environments. In addition, the delatching pull tab obviates the need for pins or screws, thereby improving manufacturing yield by reducing the likelihood that the module will be damaged during the manufacturing process. In addition, by eliminating pins or screws and a bail from the design, there are fewer moving parts that can wear out over time.

摘要： In an optoelectronic assembly in which one or more beam paths are to be aligned with a corresponding number of active optical elements, the cooperation between flexible alignment features and fixed alignment features achieves elastic averaging so as to provide the target accuracy. By averaging dimensional and positional errors over a large number of localized couplings of the flexible and fixed alignment features, elastic averaging provides the same accuracy as the more costly and complex kinematic alignment techniques.

摘要： A fiber optic transceiver (FOT) module is provided that has a circuit board attached to the FOT leadframe. The circuit board, which is typically a printed circuit board (PCB), provides several advantages over typical FOT module designs in that it provides additional surface area for mounting additional components, enables components to be moved from the motherboard into the module, allows the I/O pin count of the FOT module to be increased without increasing the width or footprint associated with the module, allows bond wires to be shortened, provides improved performance over changes in temperature, allows manufacturing yield to be improved, and enables improvements in signal integrity to be realized.

摘要： A two-part optical coupling system is provided for use in an optical transmitter (TX) module. The two-part optical coupling system has first and second optical parts and an air gap at the interface between the two optical parts. A portion of the light produced by a laser diode of the optical TX module is refracted at the air gap and is coupled by the optical coupling system into an end of an optical fiber. A second portion of the light produced by the laser diode is reflected by the air gap and is coupled by the optical coupling system onto a monitor photodiode of the optical TX. The electrical signal produced by the monitor photodiode may be used to monitor and adjust the optical output power level of the laser diode. Because the air gap is formed at the interface between the first and second optical parts, the process of forming the air gap can be incorporated into the optical coupling system manufacturing process without increasing the cost of the manufacturing process.

摘要： Independent assemblies are compliantly mounted to a force transfer mechanism to optically align and thermally couple a device under test (DUT) to a test apparatus. A first assembly includes an optical connector. The first assembly has an alignment feature and a first compliant interface. A second assembly includes a thermal control member and force transfer members coupled to a structure. A passage permits a portion of the arm of the first assembly to extend through the structure. The force transfer members provide respective seats for an additional compliant interface. The alignment feature engages a corresponding feature to align the optical connector with the DUT before the compliant interfaces compress under an external force. Compliant mounting of the assemblies accommodates manufacturing tolerances in the DUT so that contact forces on the DUT are relatively consistent and thereby enable consistent optical and thermal coupling between the test apparatus and the DUT.

摘要： An array of optical devices includes singlets diced or separated from a first diced surface and a second diced surface of a semiconductor wafer. Each singlet includes a single optical emitter or a single photosensitive semiconductor device. The singlets are identified as operationally fit before being arranged in corresponding features in a receiving region of a submount. The corresponding features of the submount are arranged to align and precisely control the pitch or separation distance between optical portions of a desired number of singlets. The use of operationally fit singlets dramatically increases production efficiency as it is no longer necessary to identify N contiguous operational optical devices in a semiconductor wafer to produce a precisely aligned array of N operational optical devices.

摘要： A method and an apparatus are provided for use in a parallel optical transmitter or transceiver to compensate for variations in optical crosstalk in an optical output power monitoring system that are caused by lasers being enabled and/or disabled. In particular, the method and apparatus cause adjustments to be made to the reference value of each optical channel based on determinations of whether one or more lasers of the other optical channels have been disabled or enabled. By making these adjustments, the average optical output power level of each laser of each channel can be maintained at a desired or required level even if one or more of the lasers of one or more of the other channels is enabled or disabled.
